Added install requirements and packages=[]

In version 61 of setuptools, there is a [breaking change](https://setuptools.pypa.io/en/latest/history.html#v61-0-0) that introduced auto discovery for packages if no `packages` or `py_modules` is explicitly specified.

To make the command `pip install --editable .` work, I had to add `packages=[],` and list all the packages used under `install_requirements`.
